An insect of the family Formicidae (illustration, illustration). This is an ant of the subfamily Formicidae, which is one of the largest species of ants found in Japan. The worker ants are 7-13 mm long. In normal ants, the size and shape of each ant is clearly different depending on the role they play, but even within a single nest, intermediate types are often found. The body is a dull black color, and the abdomen appears gray-brown due to the bristles. It is distributed from central Hokkaido to Kyushu, and is commonly seen around human dwellings except in urban areas of large cities, and is also found overseas in eastern Siberia, northeastern China, and the Korean Peninsula.
